(FR) PROCÉDÉ ET DISPOSITIF POUR DÉTERMINER UN DEGRÉ DE DÉTÉRIORATION THERMIQUE DES CHEVEUX
(DE) VERFAHREN UND VORRICHTUNG ZUM ERMITTELN EINES THERMISCHEN SCHÄDIGUNGSGRADS VON HAAR
Abstract:
(EN) Disclosed is a method with different embodiments for determining a degree of thermal damage to hair (102). The method can have the following steps: while exposing a hair sample of the hair (102) to UV or UV/VIS light (110), detecting the spectrum of at least one part of the UV or UV/VIS light which has interacted with the hair sample; comparing at least one part of the spectrum with a spectroscopic calibration model obtained using UV or UV/VIS spectra and degrees of thermal damage to a plurality of calibration hair samples; and ascertaining the degree of thermal damage to the hair using the comparison.
(FR) Selon divers modes de réalisation illustratifs, l’invention concerne un procédé pour déterminer un degré de détérioration thermique des cheveux (102). Ce procédé peut présenter les étapes suivantes : tandis qu’un échantillon des cheveux (102) est éclairé avec une lumière UV ou UV/VIS (110), l'enregistrement d'un spectre d'au moins une partie de la lumière UV ou UV/VIS ayant interagi avec l'échantillon de cheveux, la comparaison d'au moins une partie du spectre avec un modèle d'étalonnage spectroscopique obtenu au moyen de spectres UV ou UV/VIS et de degrés de détérioration thermiques d'une pluralité d'échantillons de cheveux d'étalonnage, ainsi que la détermination du degré de détérioration thermique des cheveux compte tenu de la comparaison.
(DE) In verschiedenen Ausführungsbeispielen wird ein Verfahren zum Ermitteln eines thermischen Schädigungsgrads von Haar (102) bereitgestellt. Das Verfahren kann aufweisen: während eines Belichtens einer Haarprobe des Haars (102) mit UV- oder UV/VIS-Licht (110), Aufnehmen eines Spektrums von zumindest einem Teil des UV- oder UV/VIS-Lichts, welches mit der Haarprobe gewechselwirkt hat, Vergleichen zumindest eines Teils des Spektrums mit einem mittels UV- oder UV/VIS-Spektren und thermischen Schädigungsgraden einer Mehrzahl von Kalibrierhaarproben gewonnenen spektroskopischen Kalibriermodell, und Ermitteln des thermischen Schädigungsgrads des Haars unter Einbeziehung des Vergleichs.
